  • Supporting Partner's Major Suit Opening
    Supporting partner’s major suit opening General Approach It should be a cause for joy when partner opens one of a major and you have support for the suit. Generally it is right to show this support immediately: the primary case where you may show your own suit first is when you have a game-forcing hand with only 3-card support. Direct major suit raises An immediate raise to game is pre-emptive and not a strong bid. It normally shows 5-card support and little else. Occasionally, at favourable vulnerability, it may be made with 4-card support and a weak distributional hand (you would not do it with a balanced, weak hand). A jump raise, 1M-(Pass)-3M, shows 4-card support and 7-9 points. It is not a strong raise and often described as a mixed raise. You should look at the vulnerability when making this bid: ​ ​ a bland seven points made of queens and jacks may make a single raise when vulnerable. A single raise, 1M-(Pass)-2M, shows 3-card support and 7-9 points. There is flexibility based on vulnerability: it may be a bad 10 points when non-vulnerable; it may be 4-card support if the hand is very balanced. With weaker hands and support, you can try the tactical trick of responding one no trump. The one no trump is alertable, since it is wide range but non-forcing, and if asked you should say, “wide range, 5-12 points, may be a very weak raise”. 2NT response to one major The 2NT response to 1M is not ‘Jacoby 2NT’.

TOBIN I A Digest of The One-Over-One Approach-Forcing (“Plastic Valuation”) Official and Variations INCLUDING Changes in Laws—New Scoring Rules—Play of the Cards AND A Recommended Common Sense Method “Sound Principles of Contract Bridge” Approved by the Western Bridge Association albert?whitman £7-' CO. CHICAGO 1933 &VlZ%z Copyright, 1933 by Albert Whitman & Co. Printed in U. S. A. ©CIA 67155 NOV 15 1933 PREFACE THE authors of this digest of the generally accepted methods of Contract Bridge have made an exhaustive study of the Approach- Forcing, the Official, and the One-Over-One Systems, and recog¬ nize many of the sound principles advanced by their proponents. While the Approach-Forcing contains some of the principles of the One-Over-One, it differs in many ways with the method known strictly as the One-Over-One, as advanced by Messrs. Sims, Reith or Mrs, Kerwin. We feel that many of the millions of players who have adopted the Approach-Forcing method as advanced by Mr. and Mrs. Culbertson may be prone to change their bidding methods and strategy to conform with the new One-Over-One idea which is being fused with that system, as they will find that, by the proper application of the original Approach- Forcing System, that method of Contract will be entirely satisfactory. We believe that the One-Over-One, by Mr. Sims and adopted by Mrs.

Points refer to a total value of a hand, including shape. HCP refers only to a hand’s high-card points. A natural suited bid shows 4+ cards in its suit. A natural notrump bid shows a desire to play in notrump. A non-natural bid is called an artificial bid. A convention is a commonly used artificial bid that has been given a name. Conventions are not part of Standard American, but many are commonly or nearly-universally played. A forcing bid demands a bid from partner if the next opponent passes. A forcing bid is also known as one- round-forcing. A signoff is a bid that strongly requests a pass or correction to another suit shown by the player signing off. Partner normally may not make a bid in any suit not shown by the signing-off player. A signoff usually occurs when the captain of the auction places the final contract. An invitational bid communicates that the partnership should bid a game unless partner has very minimal strength for previous actions. A game-forcing bid means that the partnership cannot play any contract below 3NT.
